If you’re at the point in your career (or even a hobby) where you’re trying to figure out what to spend your time learning next, it’s really hard to decide which skills are actually worth pursuing. The Harvard Business Review has three basic tenets to consider.

It’s a bit tough to figure out whether it’s worth your time to develop a new skill, whether that means taking online classes, going back to school, or just spending your off time practicing. So, Harvard Business Review suggests keeping three things in mind:

Driving the economic engine: We encourage executives to focus on this element first. How can you grow in a way that will help the organization succeed?

Best at: Once you’ve surfaced useful capabilities you might develop, think about whether you could become really excellent at them.

Passionate about: As soon as you’ve gotten a sense of where your potential strengths match up with useful areas for development, honestly assess how interested you are in those areas.

It’s a pretty easy set of considerations to run through and should help you decide whether a skill is worth learning or not. Really, it’s as simple as asking yourself if you’ll benefit from learning something and if it’ll actual keep your interest, but sometimes we forget to consider the simple things.
